It just takes some time, a lot of practice, a lot of attempts.
Just like that, the Thunder Magnetic Miniature busily working between the Magnetic Patterns, "smearing and erasing," gradually turned from clumsy to more skillful and lively.
Soon, the Fixed Magnetic Pattern was altered according to Mo Hua's intent.
Mo Hua then manipulated the Thunder Magnetic Miniature to exit the Letter Token along the magnetic wire and returned to his own Returning to the Source Jade Slip.
Afterward, Mo Hua picked up the Letter Token he had "altered" through the Thunder Magnetic Miniature and tried inputting a few words.
The Letter Token displayed: "I am your father."
Mo Hua tried several other lines of text, but they all ultimately displayed: "I am your father."
Mo Hua nodded, very satisfied.
This was the result after he altered the underlying Magnetic Patterns; no matter what message was input in the Letter Token, it always displayed four words:
I am your father.
